ABB wireless motion detector with almost zero energy consumption
Sunday, July 6th, 2008
ABB has developed a top-of-the-range wireless motion detector that does not consume mains electricity and is powered – for a remarkable 5-7 years - by just three standard 1.5 volt alkaline batteries.
Launched to widespread industry acclaim in Germany in 2007, the new Busch-Watchdog wireless motion detector breaks new ground in energy-efficient and cost-effective building surveillance technology.
Powered by just three inexpensive AAA alkaline batteries (the sort commonly used in portable electronic devices like digital cameras, MP3-players and remote TV controls), the new motion detector uses an innovative design to eliminate the need for costly wiring and reduce power consumption to uniquely low levels.
Battery lifespan can be extended even more - to 10 years - by using lithium iron disulfide cells instead of standard alkaline batteries.
Industry benchmark
ABB developed the product in collaboration with Busch-Jaeger and MEMS Inc, a Swiss-based company founded by former ABB engineers. Busch-Jaeger is an ABB company and a world-leading brand in low voltage building installation products and solutions. Its range of Busch-Watchdog motion detectors is widely considered the benchmark in detection capability, reliability and esthetic appeal.
Equipped with an exceptionally powerful lens and broad range of functionality, the Busch-Watchdog detects any moving object within an unparalleled 16 meters of the detector. Unrestricted by power connections, the new wireless variant brings complete freedom of placement to users. It can be attached to a building, garage, perimeter wall, porch or ceiling.
The innovation is based on low power-consuming components and embedded system technologies in three interconnected modules compromising sensors, radio communications and microcontrollers.
The microcontroller supports several power-down modes that allow the detector to go into various states of ‘sleep’ during daylight, gradually waking up as the light fades. Full recovery is instantaneous (a few microseconds) if a moving object is detected.
Busch-Watchdog wireless motion detector is one of several wireless products in the Busch-Jaeger portfolio.
